Seems he is not able to commit things properly given his situation right now and I think Trump has the ability to do that again since he is physically and and mentally fit based on my observation. Biden at some point is having this mental block sometimes during his speech and is having a hard time making decisions on his own for some reason.
Biden, according to Google, is just 81 years old, but with what I have seen in some of the recent videos of him, he acts older. The president of my country, Nigeria, is in reality older than him, but on Google, it says he is just 72 years old, which is a lie because his first daughter, Folashade Tinubu-Ojo, was 62 years old last year. Biden has health challenges and should not run for re-election. He will lose, but I still think he will give it a shot.
